  • Characteristics
TectoPrime structural construction board is a high-density chipboard with a strong, screwable core, glued with MUF glue. This board is coated on one side with an industrially applied white primer.

TectoPrime demonstrates minimal expansion and swelling under the influence of high relative humidity. The environmentally friendly UV acrylic lacquer has an extremely high dry matter content. It is applied with rollers and hardened under ultraviolet light. This treatment results in a sleek, high-quality coated surface.

TectoPrime can be used in service class 2 (limitations in temperature and surrounding relative humidity) and in biological hazard classes 1 and 2 of EN 335-3.
TectoPrime is suitable for load-bearing applications in damp conditions. This makes TectoPrime the ideal board for roof building (including prefab roofing), with the white side placed on the inside of the roof.

The white primer coating provides the perfect basis for a fast, efficient finish.
